On January 10th, the world’s first carbon fiber subway train, the Cetrovo 1.0 Carbon Star Rapid Rail, debuted in Qingdao, China.
The train was developed through a collaboration between Qingdao Metro Group and CRRC Sifang Co., Ltd. Its body, steering frame, and other key components are made from carbon fiber composite material, marking the first time this material has been used in commercial subway vehicles.

That’s a huge step forward for public transport tech. Carbon fiber makes a lot of sense here — lighter weight means faster acceleration, better energy efficiency, and potentially lower maintenance costs over the train’s lifespan. It kind of reminds me of how engineering innovations in the world speed train sector push boundaries by combining speed with efficiency. If more subway systems adopted materials like this, we could see noticeable improvements in both travel times and operational costs in the near future.
